Rubus argutus is a North American species of prickly bramble in the rose family. It is a perennial plant native to the eastern and south-central United States. Common names are sawtooth blackberry [2] or tall blackberry after its high growth.
R. argutus usually forms woody shrubs or vines, up to 2 meters (80 inches) in height, [3] with thorns on stems, leaves, and flowers. The leaves are alternate and palmately compound. First-year plants have palmate leaves with 5 leaflets while second-year plants have palmate leaves with 3 leaflets. Second-year plants develop racemes of flowers each containing 5–20 flowers. [4] The flowers are typically 5-merous with large, white petals and light green sepals, borne in mid-spring. [5] Second-year plants are also capable of growing the fruit which gives the plant's common name, the blackberry. The fruits are compound drupes which change from bright red to black at maturity. Each section (drupelet) of a blackberry contains a single seed. Second year plants die after bearing fruits, but regrow from the underground portion of the plant.
There are many species of blackberries, which are edible and differ by size. [6]
The species grows from Florida to Texas, Missouri, Illinois, and Maine. [7]
Blackberry leaves were in the official U.S. pharmacopoeia for a time and were said to treat digestive problems, particularly diarrhea. Their dried leaves make an excellent tea. [8]
The blackberry is an edible fruit produced by many species in the genus Rubus in the family Rosaceae, hybrids among these species within the subgenus Rubus, and hybrids between the subgenera Rubus and Idaeobatus. The taxonomy of blackberries has historically been confused because of hybridization and apomixis, so that species have often been grouped together and called species aggregates. For example, the entire subgenus Rubus has been called the Rubus fruticosus aggregate, although the species R. fruticosus is considered a synonym of R. plicatus.
Rubus idaeus is a red-fruited species of Rubus native to Europe and northern Asia and commonly cultivated in other temperate regions.
Rubus spectabilis, the salmonberry, is a species of bramble in the rose family Rosaceae, native to the west coast of North America from west-central Alaska to California, inland as far as Idaho. Like many other species in the genus Rubus, the salmonberry plant bears edible fruit, typically yellow-orange or red in color, resembling raspberries in appearance.
Rubus phoenicolasius is an Asian species of raspberry in the rose family, native to China, Japan, and Korea.
Rubus caesius is a Eurasian species of dewberry, known as the European dewberry. Like other dewberries, it is a species of flowering plant in the rose family, related to the blackberry and raspberry. It is widely distributed across much of Europe and Asia from Ireland and Portugal as far east as Xinjiang Province in western China. It has also become sparingly naturalized in scattered locations in Argentina, Canada, and the United States.
Rubus pensilvanicus, known commonly as Pennsylvania blackberry, is a prickly bramble native to eastern and central North America from Newfoundland south to Georgia, west as far as Ontario, Minnesota, Nebraska, and Arkansas. The species is also established as a naturalized plant in California.
Rubus laciniatus, the cutleaf evergreen blackberry or evergreen blackberry, is a species of Rubus, native to Eurasia. It is an introduced species in Australia and North America. It has become a weed and invasive species in forested habitats in the United States and Canada, particularly in the Northeast and along the Pacific Coast.
Rubus armeniacus, the Himalayan blackberry or Armenian blackberry, is a species of Rubus in the blackberry group Rubus subgenus Rubus series Discolores Focke. It is native to Armenia and Northern Iran, and widely naturalised elsewhere. Both its scientific name and origin have been the subject of much confusion, with much of the literature referring to it as either Rubus procerus or Rubus discolor, and often mistakenly citing its origin as western European. Flora of North America, published in 2014, considers the taxonomy unsettled, and tentatively uses the older name Rubus bifrons.
Rubus ursinus is a North American species of blackberry or dewberry, known by the common names California blackberry, California dewberry, Douglas berry, Pacific blackberry, Pacific dewberry and trailing blackberry.
Rubus ulmifolius is a species of wild blackberry known by the English common name elmleaf blackberry or thornless blackberry and the Spanish common name zarzamora. It is native to Europe and North Africa, and has also become naturalized in parts of the United States, Australia, and southern South America.
Rubus pubescens is a herbaceous perennial widespread across much of Canada and the northern United States, from Alaska to Newfoundland, south as far as Oregon, Colorado, and West Virginia.
Trautvetteria is a genus of flowering plants in the buttercup family. Today it is often considered a monotypic genus, containing only one species, Trautvetteria caroliniensis, which is known by the common names Carolina bugbane, false bugbane, and tassel-rue. A second species, T. japonica, is now generally considered a variety of this species. The genus is named for the botanist Ernst Rudolf von Trautvetter.
Rubus canadensis is a North American species of flowering plant in the rose family known by the common names smooth blackberry, Canadian blackberry, thornless blackberry and smooth highbush blackberry. It is native to central and eastern Canada and the eastern United States.
Rubus flagellaris, the northern dewberry, also known as the common dewberry, is a North American species perennial subshrub species of dewberry, in the rose family. This dewberry is distributed across much of Canada, Mexico, and the United States. It grows in diverse habitats ranging from drier savannas to temperate deciduous forests.
Rubus allegheniensis is a North American species of highbush blackberry in section Alleghenienses of the genus Rubus, a member of the rose family. It is the most common and widespread highbush blackberry in eastern and central North America. It is commonly known as Allegheny blackberry.
Rubus vestitus is a European species of brambles in the rose family, called European blackberry in the United States. It is native to Europe and naturalized along the northern Pacific Coast of the United States and Canada.
Rubus bifrons, the European blackberry or Himalayan blackberry, is a European species of flowering plant in the rose family. It is widespread across much of Europe and naturalized in scattered parts of North America. It is sometimes considered to include the species R. armeniacus.
Rubus elegantulus, the showy blackberry, is an uncommon North American species of flowering plant in the rose family. It grows in the northeastern and north-central United States and eastern Canada.
Rubus setosus, the bristly blackberry, is a North American species of flowering plant in the rose family. It is widespread in much of central and eastern Canada and the northeastern and north-central United States
Perideridia americana is a species of flowering plant in the family Apiaceae known by the common names eastern yampah and wild dill. It has been found in 12 Midwestern United States, and is listed as threatened or endangered in at least 3 of them. In Missouri it is a conservation species of concern.
